The walnut (Juglans spp.) is an appreciated nut that belongs to the Juglandaceae family. The fruit includes four main parts: the kernel, the skin, the shell, and the green husk. It is widely cultivated due to its edible kernel. In walnut production centers, high amounts of the husk as an agro-forest waste product are produced and discarded away. Recently, it has been demonstrated that the walnut green husk could be valued as a source of different natural bioactive compounds with excellent antioxidant and antimicrobial properties. Regarding this respect, in this contribution, the current scientific knowledge on the antioxidant and antiradical activities, various identified and isolated individual chemical constituents, as well as the functional applications of the walnut husk with more emphasis on the Persian walnut (Juglans regia L.) are reviewed.
核桃（Juglans spp.）是一种受欢迎的坚果，属于胡桃科。果实由四个主要部分组成：核仁、果皮、壳和绿色的内果皮。由于其可食用的核仁，它被广泛种植。在核桃生产中心，会产生大量的作为农林废弃物的内果皮，并被丢弃。最近，已经证明核桃的绿色内果皮可以作为不同天然生物活性化合物的来源，具有出色的抗氧化和抗菌性能。关于这方面，在本贡献中，综述了当前关于抗氧化和抗自由基活性、已鉴定和分离的个别化学成分，以及核桃内果皮的功能应用的科学知识，重点介绍了波斯核桃（Juglans regia L.）。
